And think how you are going to get down once you are dangling in the
harness. You don't have long dangling before blood starts to pool in
your legs and nasty physilogical things start to happen, including
death.

The answer to that is to use a rate of descent control device, rather
than a fixed length of rope. You still hit the ground if you fall, but
slowly enough for it not to hurt.

I have a safety harness which works this way by having a long length
of thick velcro which slowly rips apart. (At least in theory, I've
never needed to try it, and it's a one-use only.) If you have to work
by yourself, check the drop distance from the suspension point so you
aren't going to be left dangling in mid-air. Make sure you know how
to put on and adjust the harness correctly, unless you want a set
of crushed nuts (a common injury with falls using safety harnesses
which were not correctly adjusted beforehand). Also, the suspension
point needs to be able to take to arrest force (many times your weight).
